Ok these people know science thank you so much ☺️ ☺️ ☺️ ☺️ ☺️ ☺️ ☺️ ☺️ ☺️ ☺️ ☺️ ☺️ ☺️

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
